Jsf+redirecting

I have a jsf portlet, and I have the com.sun.faces.portlet.INIT_VIEW in my portal.xml file set to go to my default page. My issue now, is that the business wants to display a different page as the default page based on some requirements. How would I route the user to 1 page or another page bases on these requirements? I can't use the redirect method inside the default pages constructor. I tried setting the viewId of the UIViewRoot using the below code, but that didn't do anything either. Here is the code I tried
FacesContext facesContext = FacesContext.getCurrentInstance();
Application application = facesContext.getApplication();
ViewHandler viewHandler = application.getViewHandler();
UIViewRoot view = viewHandler.createView(facesContext, "/alternate_page.xhtml");
facesContext.setViewRoot(view);
facesContext.renderResponse();Can anyone help me with this?
thanks!!

JSF lifecycle is somewhat complex, and generally speaking you are better of by playing by it's rules instead of calling .redirect() at arbituary point. Good extension point for adding parameters to redirects is getActionURL() method of the ViewHandler implementation.
However, if you want to simply refresh the page and pass some additional parameter you can use commandLink without action and nest f:param elements, e.g.
<h:commandLink value="Heelp!">
<f:param name="showHelp" value="true">
</h:commandLink>

[JSF] redirect to a PDF or XLS file.

How to make redirection to some new file?
Could you make that example in JSF?
I can't find where i can make a PAGE there...
For example I want to make excel file with help of POI and make an output to the screen. With the help of EventResult I made this on UIX, but not JSF...
Thanks in Advance.

for PDF, try this out...
http://www.apple.com/downloads/dashboard/status/dashclipping.html
allows you to use a URL to display in a window. nice widget. I use it to check a site or two, but i have tested on local PDF files, and it works fine...
eg:
URL = file://localhost/Users/usernamehere/Desktop/example.pdf

JSF - redirect with parameter

Hi All,
I have a JSF application that is consists of 5 pages. The first one is clear JSP page where the user have the possibility to logged in the application. After the user has been successfully authorized the JSF page redirects to JSF page that displays list of items.So far so good, but when the list of items contains only one item I want to redirect directly to the third page that displays the description of the selected item from the second page. The second page pass the item id with the following code:
     <h:commandLink action="ItemDescription" actionListener="#{itemDesc.processAction}">
          <f:param name="item_id" value="#{MyItem.id}"></f:param>
          <h:outputText value="#{MyItem.name}"></h:outputText>
     </h:commandLink> Currently I can redirect to the third page by using FacesContext.getCurrentInstance().getExternalContext().redirect("Third.faces") but I don't know how to set the parameter item_id.
Do you have any suggestions?

Pass it along as a query parameter:redirect("Third.faces?item_id=" + id);

JSF 2.0 no ajax redirection

Hi all,
When I save a object with the commandButton I will be redirected to the value I return. But this an ajax redirection and I want a hard redirection so you see the page in browser.
How can I make this possible?
Thanks in advance.

Oh, I see your point is to display the URL on the browser itself for the page, where you are right now.
But, before saying anything you need to understand that for a normal navigation JSF will always show a previous page URL in the browser, from which the request was submitted actually. And, this is normal and expected as JSF keeps a track of all of the page views and restore the view for the page from which request is started.
But, if you use redirect instead of normal navigation and this can be done by putting a simple </redirect> next to the entry of navigation of each page inside navigation.xml, this will actually redirect original request.
There are lots of associated things you need to be worried, to display the page URL in the browser...
- Every page will be redirected for a requests, resulting you would not be able to pass request variables.
- Each page will be processed twice to render and similary others points, which would be relevant just because of JSF redirection.

JSF 1.2 Session Timeout Issue

I am using using:
JSF- Sun RI (1.2)
Websphere (6.1)
Facelets (1.?)
RichFaces (3.3.2)
I am having an issue with session timeouts that shows up in two different ways:
Scenario 1) the client makes an ajax call after the session has timed out
Scenario 2) the client makes a standard request after the session has timed out - navigating to a new page
I seem to be able to address one or the other, but I can't seem to find a solution that fixes both scenarios.
For Scenario 1, I have the client-side A4J.AJAX.onExpired function defined and that is currently working for session timeouts that are discovered via an ajax request.
However, if I start making changes to try and address the other scenario, it seems to break the A4J javascript function.
For Scenario 2, I have tried a number of suggestions that I've found online:
1) I've tried to configure the error page in web.xml:
<error-page>
     <exception-type>javax.faces.application.ViewExpiredException</exception-type>
     <location>/timeout.jsf</location>
</error-page>
However, anything I seem to try around this solution still winds up with a ViewExpiredException. I've tried to have timeout.jsf redirect to the login page and I get a ViewExpiredException on the login page when the redirect happens. I've tried to just render a timeout page with a link the user can click on to go to the login page and that fails as well.
2) I've tried the phase listener and had little success too.
3) I tried a NavigationHandler
One thing I did have working, I believe, was with the phase listener approach, but I had a difficult time displaying a session timed out message upon redirect, but not the first time the user visited the page.
I'm relatively new to JSF and probably don't understand the app life cycle well enough, I guess, but is there a solution that addresses all of these issues:
1) works for AJAX calls
2) works for actual navigation
3) sends the user back to the login page with some indication as to "why", but gracefully handles the first visit to the login page (or a logout)
Thanks for any suggestions you can offer.

Sorry, but I have to disagree. Loading JavaScript at the beginning of your page would only make the page load slower (and "ruin" the user's experience when they see the page being loaded steadily) and also cause unforeseen issues than to leave it at the bottom of your page.
Big companies like Google (1999), Yahoo (2000), Oracle (2001) and many others are doing the opposite to what you have said. Look at the way they load their JavaScripts and you'll see.
It's also good practice to zip your content from the server before sending it to the client's web browser to increase performance. Of course, this will depend on whether your web browser supports methods such as gzip, deflate, etc... and whether you use HTTP or HTTPS.
Lastly, another bad practice I often see Java programmers do is write the following all over the places:
setString, setInt, setDouble, etcInstead of using an existing feature of Java to do the same in one procedure, as in:
public static void setParameters(PreparedStatement preparedStatement, Object... values)
   throws SQLException
   for (int i = 0; i < values.length; i++) {
      preparedStatement.setObject(i + 1, values);
Then just call *setParameters* whenever you need it instead of writing multiple setString, setInt, etc statements everywhere...

Page Refresh Issue in JSF

Hi All,
Kindly treat this on high priority.
Here's the "setup" :-
Page Refresh in JSF Application
When a user hits refresh, the behavior is different depending on if the current page was loaded via GET(outputLink) or POST(commandLink/commandButton).
If a GET, the browser simply re-asks for the page re-using the current URL.
But If a POST, the user is asked, usually, if they want to re-submit their data to the server.
The resubmitting of data happens for the last request generated by the POST method (correct me if i am wrong here)
How can one avoid doing this?
Heres "the performance" :-
I googled out, only to come across words like "jsf redirect tag"
I tried putting it in my navigational rule, only to get the error "Page could not be found. Internal Server Error 500"
Could i get my hands on "the prestige" ?
Thanks & Regards,
Darshan Shroff

Thanks for the reply.
I could not understand the logs.
Can you make any sense of this ?

Page security on glassfish

Hi ,
I'm using Jdev 11.1.2.3 and glassfish as webserver
I want to make one entry login page for my application deployed on glassfish, I found a solution when the application was deployed on weblogic using ADF Security and authenticated role, but in glassfish ADF Security is not enabled.
for exp, if i have :
login.jspx
index.jsf
app.jsf
in the url when i enter :
http://localhost:8080/MyERP/faces/index.jsf ==> redirect to http://localhost:8080/MyERP/faces/login.jspx
same thing
http://localhost:8080/MyERP/faces/app.jsf ==> redirect to http://localhost:8080/MyERP/faces/login.jspx
because in the login I will determiner the user profile
Thanks

because I implemented Glasfish security role mapping on my application, the solution I found to logout my application is to kill the browser process, in that case the user must enter new user login :
public String browserKill() throws IOException {
String os = System.getProperty("os.name");
if (os.contains("Windows")) {
Runtime.getRuntime().exec("taskkill /F /IM chrome.exe");
Runtime.getRuntime().exec("taskkill /F /IM iexplore.exe");
Runtime.getRuntime().exec("taskkill /F /IM firefox.exe");
Runtime.getRuntime().exec("taskkill /F /IM safari.exe");
Runtime.getRuntime().exec("taskkill /F /IM opera.exe");
} else {
// Assuming a non Windows OS will be some version of Unix, Linux, or Mac
Runtime.getRuntime().exec("kill `ps -ef | grep -i firefox | grep -v grep | awk '{print $2}'`");
Runtime.getRuntime().exec("kill `ps -ef | grep -i chrome | grep -v grep | awk '{print $2}'`");
Runtime.getRuntime().exec("kill `ps -ef | grep -i safari | grep -v grep | awk '{print $2}'`");
return null;

Https Problem - ClosedChannelException

Hello,
I have a webservice that I deployed into the standalone OC4J. I then enabled https according to the instructions given in http://download.oracle.com/docs/cd/B25221_04/web.1013/b14429/configssl.htm !
When I'm calling the webservice via Firefox or Opera everything works well.
But when I'm using Internet Explorer, I get this Exception:
"Exception in NIOServerSocketDriver:selectForRead" (java.nio.channels.ClosedChannelException)
at java.nio.channels.spi.AbstractSelectableChannel.configureBlocking(AbstractSelectableChannel.java:252)
and shortly after it the following:
"Exception in SelectionKey cancel"
(java.lang.NullPointerException)
at oracle.oc4j.network.ServerSocketAcceptHandler$IdleHandlers.closeIdleHandler(ServerSocketAcceptHandler.java:583)
Both Exceptions come randomly and every trial on different program- and timesteps, so there's no real locating of the error possible!
Can anyone please help me to understand what happens there and how to solve this problem.
Thank you very much!
Sebastian

[...]- never tried Opera or Firefox, but with IE I have the same problem (ADF Faces 11 app. on OC4J 11 + Acegi security framework)
did you ever solve this problem, and if so - how ?
The only way I can see - is to avoid

So, can someone explain why this error happens, and how to avoid this in one more elegant way ?

Returning from a JSF flow with faces-redirect

I'm using Glassfish 4.1 with JSF 2.2.9. I can't figure out how to return from a JSF flow with a redirect. I've tried this in the flow definition xml:
<flow-return id="returnFromFlow">
<from-outcome>/index.xhtml?faces-redirect=true</from-outcome>
</flow-return>
This does the redirect but results in navigation errors on the page, specifically the button that enters the flow again: "Unable to find matching navigation case from view ID '/index.xhtml' for outcome 'select-person'" (the flow is called select-person).
I've also tried appending faces-redirect=true to the action of the commandButton that exits the flow. Now the flow does not exit, it reloads the current page within the flow and says "Unable to find matching navigation case with from-view-id '/select-person/select-person.xhtml' for action 'returnFromFlow?faces-redirect=true' with outcome 'returnFromFlow?faces-redirect=true'"
Exiting the flow with h:link works, but I want to be able to call an action and submit form values with the button so that isn't a good workaround for me.
What's kind of interesting is that navigating between views within the flow DOES work with faces-redirect=true. I can add a "step2" node, and a commandButton with action="step2?faces-redirect=true", and it works. It's just exiting the flow that does not work.
Any ideas?

Hi Frank,
Thanks so much for your response.
Yes, since the user can do a commit prior to exiting my edit task flow, option 1 will not work for me.
Option 2 sounded feasible, but jdeveloper would not let me set the restore point to true, since my btf didn't require a transaction. Is there a step I'm missing here??
The thing that is really getting me when return via the cancel button from this edit task flow, back to my parent task flow, the record pointer is always moving back to the beginning of the data set in my parent task flow. For example,if I have a data set
rec1, rec2, rec3..
On my parent taskflow call it browser task flow, I navigate (via the next button) to rec3, and I click edit. At this point, my edit task flow kicks off, and since both task flows share the same data control, the edit task flow rec pointer is the same as the browse one.
Okay I decide I don't want to change anything in my rec3, so I click cancel.
At this point, when I return back to the navigator task flow, it points me back to rec1 ..
HOwever, the savepoint seems to fix this. When I set my cancel return from edit taskflow to savePoint = true, the rec pointer stays in the correct spot. However, I cannot always do this, because the user can make iterative saves in the edit task flow which (based on your previous email) stales out the savepoint id.
Question, so in this case, how can I make the parent browser task flow call stay on the same record I was just editing, opposed to going back to the beginning of the data set(ie. rec1)??

How-to get attributes from one JSF page redirected to another?

How do I send information from one JSF page when the navigation rule redirects it to another?
When JSF navigation does a forward I can use request.setAttribute() in the from-page and then use request.getAttribute() in the to-page, but this doesn't work with <redirect/>.
Regards,
Al Malin

The process scope in ADF Faces solves this. See:

How to implement Post redirect Get Pattern in JSF

Hi All,
Will Post-Redirect-Get pattern solves the duplicate form submission in JSF 1.1 ? . Kindly provide valuable suggestion or implementation detail on PRG.
Regards,
Dev

Continuation of this thread:How to prevent dupilcate form submission in JSF 1.x
No, the PRG pattern will only make it less likely to happen. The user is still free to navigate back in the browser history to where the POST happened and then perform it again.

URI Redirecting Problem in JSF ActionListener !!Please help!

Hi, i have 2 pages: A.jsp and B.jsp.
I have a command link in A.jsp, and its code is like this:
<h:commandLink actionListener="#{navigator.goBSite}">
     <h:outputText value="GoB" />
</h:commandLink> in the action listener goBSite(ActionEvent e), i need to clear some flag values in session beans, so i cannot jump to B.jsp simply, i need to use an actionListener, and in the actionListener, first clear the flags and then redirect the page to B.jsp. i tried the code below:
HttpServletResponse response = (HttpServletResponse) context
                    .getExternalContext().getResponse();
          try
               response.sendRedirect("/Platform/publish/registry.faces");
          catch (IOException e1)
               e1.printStackTrace();
          }But it does not work, and an exception with the message "java.lang.IllegalStateException: Cannot forward after response has been committed" is thrown, so i think this method can only be used in servlet.
I think i can write a C.jsp, i write the java code in C.jsp to clear the flag values, and then redirect the page the B.jsp, this may be a solution, but not a good one.
So is it possible to redirect my page in my actionListener?
Best Regards:)
Robin

Hi Robin,
First, let me make sure I understand your issue. You have two JSPs A (A.jsp) and B (B.jsp) where A contains a command link which should take you to page B, and you want to manipulate some flag in the a session bean,(sbean). If I miss understood your issue you may stop here :-)
In the JSF life cycle phase, action and actionListeners are processed during the "Invoke Application" phase. You may assign one or more actionListeners to a component, in your case the commandLink, and a single action. The actionListeners perform user interface logic and NOT navigation, where as actions perform business logic (you can get for session bean and update it in this code) and it returns an out-come string (navigation). The processing of actionListeners precede the processing of the single action method. The actionListener's interfaces is public void myActionListener(ActionEvent e), while the action's interface is the public String myAction(), where the returned string is an outcome string defined in the a navigation-rule element in the faces.configation file.
In a nutshell you need to switch from the actionListener to the action interfaces and create/update and add some configuration to your faces-config file (managed bean and nagivation)
Here's a a quick and dirty example:

JSF Web Application - endless redirecting loop

I've created a simple JSF WebApplication, just one page, one static text. When I deploy it to the bundled server, everything is OK. When I deploy it to a remote server, that I have access to (Sun Java System Application Server Enterprise Edition 8.1_02), and I browse to its URL (http://server:port//Webapplication), the browser shows me an error. IE just displays Page cannot be displayed error, Firefox tells me, that the app. ended up in a redirection loop.
When I browse to /Webapplication/faces/Page1.jsp, everything is ok.
What can be wrong?

Hello
We are looking at doing the same thing (iviews in Sharepoint)
Any luck in solving the problem ?

JSF - Map area redirect

Hy all.
I have two problems whith JSF and Seam.
I've define several areas on an image to choose points of impact in an accident
Code is like this:
<center><img src="myImage.jpg" usemap="#ImpactLateralGauche" border="0"/></center>
<map name="ImpactLateralGauche">
<c:forEach var="degat" items="${myBean.listeDegats}">
<area shape="circle" coords="${degat.coordonnees}" alt="${degat.libelle}" href="#{myBean.addDegat(degat)}" />
</c:forEach>
</map>Don't worry, the code
href="#{myBean.addDegat(degat)}"doesn't work.
First question:
Why when i load my page, JSF call the method addDegat as many times there has occurrence???
I don't want this to append.
Second question:
Do you know how i can use the Href tag to call my method instead of a redirection page??
Thank's for your help.

I imagine a custom component might be the way to go here.

JSF URL redirection

I want the user to type in the browser
http://my.website.com
which would be forwarded to this.
http://my.website.com/CTOpsProd/faces/frames.jsp
It would be great if someone could tell me a simple way to do this using JSF or websphere setup
thanks

Just add JavaScript code like location = 'CTOpsProd/faces/frames.jsp'; to Your index.jsp
or use <jsp:redirect> tag.
I want the user to type in the browser
